What I should have said is that these are music cds that are in mp3
format that I downloaded. Some will mount, some won't. Using the command
line

[root@localhost ~]# mount -t iso9660 /dev/sr0 /home/chris/cd
mount: block device /dev/sr0 is write-protected, mounting read-only

Some will mount just fine, however others show:

[root@localhost ~]# mount -t iso9660 /dev/sr0 /home/chris/cd
mount: block device /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so
